Treatment of E. coli 50S ribosomal subunits with low doses of bis-(2-chloroethyl)-methylamine ("nitrogen mustard") leads to formation of a number of intra-RNA and RNA-protein cross-links. After partial digestion of the cross-linked subunits with cobra venom nuclease, followed by destruction of the protein moiety with proteinase K, complexes containing the intra-RNA cross-links were isolated by two-dimensional gel electrophoresis. The individual complexes were subjected to oligonucleotide… CONTINUE READING
